GPT-5-Codex is the newest, released Sep 15, 2025. Pixtral Large (25.02) came out Apr 8, 2025; Qwen3-Coder 480B-A35B Instruct came out Apr 2025. Knowledge cutoff: GPT-5-Codex Sep 30, 2024, Qwen3-Coder 480B-A35B Instruct Apr 2025.
How do you decide the winner?
Each model gets a 0–100 score on capability (50%, independent benchmark results); price (25%, blended price per million tokens (3 input : 1 output), log scale); inputs & features (15%, image, PDF, audio and video input, tool calling, structured output and reasoning); context window (10%, maximum tokens per request, log scale). Dimensions missing for any model are dropped and the remaining weights rescaled, so every model is judged on the same evidence. Specs and prices come from public model listings and the labs’ own API pages; capability scores come from independent benchmark runs. Data updated Oct 4, 2026.
